Assessment Location
Please indicate to the UL project planner if you would prefer an on-site assessment of your
facility’s procedures and controlled documents during your QAR surveillance or reassessment
audits or a desktop assessment to be performed at UL.
Assessment Details
Project Plan
You will be notified by a UL project planner to determine the assessment location and
also if any additional documentation is required. You will also be contacted by UL
Customer Service, who will arrange for all necessary applications and financial
aspects to be completed prior to initiation of the investigation.
Contract Review
UL will review your application to ensure that the following items are included:
identification of the Ex products covered by the IECEx CoCs issued by UL, UL’s
nominated application form, copies of the applicant’s internal procedures for use,
display and control of the IECEx Conformity Mark, a controlled document detailing the
design of the IECEx Conformity Mark and the signed License agreement between UL
and Manufacturer which shall include reference to the manufacturer’s agreement
with the Terms and Conditions as detailed in OD 023.
If during the contract review any of the requirements are not met, UL will inform you
and allow you to review the application. If the results of the contract review are not
positive, then we will inform you within 48 hours of arriving at this decision. You may
submit additional information, withdraw their application, or we may terminate the
application where the IECEx requirements are not met.
IECEx CoC Verification
UL will then verify that the nominated IECEx CoCs are current and are only issued by
UL. If there are CoCs issued by other ExCBs, then the manufacturer will need to
request a separate IECEx Conformity Mark License from each ExCB that holds their
CoC.
If during the contract review any of the requirements are not met, UL will inform you
and allow you to review their application. If the results of the contract review are not
positive, then UL will inform you within 48 hours of arriving at this decision.
Assessment and Audit of Procedures
UL will coordinate the review of manufacturer’s procedure documents either at the
manufacturer’s facility during their Quality Assurance Assessment or Surveillance
audits or through a desktop audit. The assessment shall ensure that the IECEx
Conformity Mark is only associated with products covered by the IECEx Certificates
of Conformity listed in the application, shall include a review of the promotional
material where the IECEx Conformity Mark is to be used, shall include identification of
the senior position with the responsibility and authority to control the use of the Mark
within the applicant’s organization and ensure that the requirements of the Terms and
Conditions in OD023 are met.
If the results of the assessment/audit are not positive, UL will inform the manufacturer
within 48 hours of arriving at this decision. The manufacturer may submit additional
or revised procedures or may withdraw their application.

also check that the design is submitted in the form of a controlled document.
Upon successful completion of the review, UL will indicate the acceptance of the
design to the applicant in an email and create a copy of the controlled document for
our records.
If the results of the review are not positive, then UL will inform you within 48 hours of
arriving at this decision. You may submit a revised document with the modified Mark
for review by the ExCB or may withdraw your application.
IECEx Conformity Mark License Issuance
After successful completion of the above items, the IECEx Conformity Mark License
is issued and the manufacturer is sent a copy of the license via email. The
manufacturer may request to have a hardcopy of the license sent as well.
Surveillance Audit and Reassessment Plan
The Licensee agrees to an extension of its existing on-going surveillance audits, as required
by IECEx 02, to allow UL the opportunity to verify the Licensee’s compliance with the IECEx
Conformity Mark Regulations, Operational Documents, IECEx OD 422 and OD023.
Unit Verification
The assessment of the applicant’s proposed use of the mark is conducted at the
assessment/testing stage of processing the Unit Verification Certificate application. The
Mark may only be used on the product marking covered by the Unit Verification Certificate
and cannot be displayed on promotional material, websites, etc.
Suspension and Withdrawal of IECEx Conformity Mark Licenses
An IECEx Conformity Mark License may be suspended or withdrawn if:

It has been issued in error

The holder requests cancellation

It is used in a misleading way or

It is used by a non-approved third party
Complaints and Appeals
All complaints shall first be brought to the attention of UL. If a complaint cannot be resolved
by UL, the manufacturer may appeal the resolution of a complaint in writing to the ExTL and
the Program Owner. The Program Owner shall respond to the appeal in writing. If the
Program Owner cannot satisfactorily resolve the appeal, the manufacturer may appeal to the
IECEx Management Committee as described in IECEx 01. If an appeal cannot be resolved at
the level of the IECEx Management Committee, an appeal may be lodged with the CAB
whose decision is final. The manufacturer shall cover all costs arising from appeals.
